TWO-WHEELED VEHICLE.

SPECIFICATION forming part of Letters Patent No. 375,381, dated December27, 1887.

' Application filed May 11, 1887.

To all whom it may concern:

Be it known that we, BENJAMIN S. PORTER and CLARENCE W. PORTER, citizensof the United States, residing at Red Oak, in the county of Montgomeryand State of Iowa, have invented certain new and useful Improvements inRoad-Carts; and we do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing bad to the accompanying drawings, and to letters or figures ofreference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of this invention and is abottom View. Fig. 2 is a vertical section. Fig. 3 is a detail and aperspective view of the spring.

This invention has relation to two-wheel vehicles; and it consists inthe construction and novel combination of parts, as hereinafter setforth.

In the accompanying drawings, the letter A designates the shaft-bars,and B the seat-bars connected to the shaft'barsin front of the seat, asindicated at O. The shaft-bars are properly braced across by a bar orbars, D, and by the axle to which they are connected. The seat-bars areof less width near the seat than the shaft-bars and are provided witheyes or bearings E.

I F indicates a pair of torsion-springs of obtuse angular form adaptedto support the seat from the shafts, one on each side. The main lengthand horizontal portion of each spring F (indicated at G) is seated inclips or bearings H, which serve to secure the springs to the shaft-barand also allow it torsional mo- Serial No. 237,870.

tion. I In front of the forward bearing H the front end of the spring isset transversely in the form of a short arm, I, which engages theshaft-bar and acts in opposition to the movement of rotation which thespring would other wise have in the bearings H, so that torsionalelasticity is secured. The rear arm, K, of each spring extends upwardand rearward obliquely from the horizontal portion G, forming an ob tuseangle therewith, as indicated, and at its extremity this arm is setrearwardly, as at L, to enter the eye or bearing E of the seat-bar andengage the same, playing back and forth therein as the seat vibratesdown or up under the weight imposed when the vehicle is in motion.

Having described this invention, what we claim, and desire to secure byLetters Patent, 1s-

1. The combination,with the shaft-bars and seat bars connected thereto,of the obtuseangled torsion-springs F F, having their horizontalportions connected to the shaft-bars by bearings, the forward endsengaging the shaftbars and the rear ends set rearwardly and engagingbearings of the seat-bar, substantially as specified.

2. The side torsional springs, F, having the short terminal transversearm and the oblique arm K, forming an obtuse angle with the horizontalportion G, substantially as specified.

In testimony whereof we affix our signatures in presence of twowitnesses.
